How to Create Malware Protection Policies

  • Last updated on

You can configure the Malware Protection policy to either scan or not scan traffic by default.  Scanning is done according to the virus scanner configuration and, if  an Advanced Threat Protection (ATP) license is present, also by the ATP engine. When performing an ATP scan, a hash DB lookup is performed before a user receives a downloaded file, which compares a hash of the file with the Barracuda database to see if it is a malicious file. Simultaneously, the file is uploaded to the Barracuda Advanced Threat Protection (ATP) cloud if the file size is 10 megabytes or less (see Advanced Threat Protection (ATP) for general information). Depending on the behavior of the file, it is assigned a threat level that is transmitted to the appliance. The file is then either blocked or delivered.

Create an Explicit Malware Protection Policy 

  1. (On the Control Center) Go to CONFIGURATION > Configuration Tree > Multi-Range > Global Settings > Global Firewall Objects.
  2. (On a CloudGen Firewall) Go to CONFIGURATION > Configuration Tree > Box > Assigned Services > Firewall > Forwarding Rules.
  3. Click Lock.
  4. In the left menu, expand Policy Profiles.
  5. Select Malware Protection. The Malware Protection Policies window opens.

  6. Select the profile you wish to create the policy for. The policy list appears under the corresponding tab in the lower window.
  7. To add a new policy, click the plus icon (add_ico.png) at the top right of the lower window. You can also right-click the list and select Add Policy
  8. Specify values for the following:
    • Name – Enter a descriptive name for the explicit policy.
    • Description – Enter a description for the policy.
    • Action – Select Scan or Do Not Scan.
    • Source / Destination IP / Network Criteria – Select the source and destination network, or select <Explicit Network> and enter an IP address / network or a domain that gets resolved to an IP address for the matching.
    • Application Criteria – Define the application match condition. Add an application the policy should apply to, or create explicit applications. To open the selection menu, double-click the corresponding field. Selecting applications in the application editor works similar to the process in the objects configuration for the application rule set.
